Cat Dewormer Buyer’s Guide
Using over the counter dewormers for your cat isn’t just about quality, it also has to do with the type of parasites your cat is infested with. In this buyer’s guide, I’ll go over the different kinds of cat dewormers available, how they work, and how to choose the right cat dewormers for effective treatment.
How Cats Get infected with Parasites
Even indoor cats can require cat dewormers from time to time, especially if they’re caught rifling through their cat litter to eat their feces. Typically, cats will become infected with worms by ingesting an infected flea as they groom. They can also get parasite infections by eating worm eggs in the environment. Fortunately, there are many types of medications that can successfully treat an infection over the course of ten days. While the initial treatment will eliminate parasites in a matter of hours, repeat treatment is needed to kill any eggs still in the intestinal tract. These eggs will hatch in ten days, which is why most dewormers require a second dose.
Types of Worm Infestations
There are many kinds of parasites that your cat may come into contact with, especially if your cat is sort of an outdoor pet.
Below, you’ll find a list of the most common types and symptoms your cat may experience.
Full grown roundworms can measure in at three to six inches long and will begin by infesting a feline’s intestines. As the roundworms grow, they begin to reproduce and hatch, spreading to the organs in the body.
Roundworms can enter a cat’s body when they’re still in their larval stage. The parasitic eggs can be found outdoors in birds and rodents, which many cats enjoy hunting and killing. The eggs can also be found in the feces of infected animals or in the soil. Even an indoor cat in perfect health can get this type of worm, especially kittens. A kitten can become infected with roundworms simply by drinking its mother’s milk.
People can get roundworms and some other types of parasites from their infected pet, which is why immediate treatment is essential.
Symptoms of a roundworm infestation in a cat can include:
- A dull coat
- Poor health
- Decreased appetite
You may even see worms in your cat’s vomit or stool. Typically, a kitten’s belly will become hard and enlarged, while the rest of their body remains malnourished due to the parasites remaining in the intestinal tract.
Tapeworms, also known as flatworms, get their name because they’re segmented and flat. As they grow, some of the segments of the parasite will break off and are passed through the stool. A cat can become infested with these worms if they consume animal feces or drink water that has been infected by tapeworm eggs. A cat can also become infected if they eat birds, rodents, or fleas that are infested with tapeworms.
Symptoms of tapeworm infestation in a cat includes:
- Excessive biting and licking of the anus
- The appearance of small tapeworm segments in the hair around the anus or in the feces.
These worms love to call the intestines home and will suck the blood from the intestinal walls, which can cause anemia, bleeding, and inflammation of the intestines, which can be hard on your cat’s health.
A kitten can get hookworms by drinking its mother’s milk, or they can become infected by coming into contact with the larvae, which is found in contaminated feces, water, litter, sand, or soil.
Symptoms of a hookworm infestation in a cat can include:
- Sores and lesions on the pads of their paws
- Stool that’s tarry and dark
- Poor appetite
- Weight loss
Additionally, a cat may have pale lips and nostrils.
Since these worms can do some serious damage to your cat’s health, you’ll need to purchase products that are specifically designed for hookworms and treat your cat immediately.
Lungworms in a cat can infect the lungs, which can result in severe breathing problems. A cat can become infected if they eat the larvae, which can be found in infested rodents or contaminated water.
Symptoms of lungworms include:
- Fluid build-up in the lungs
- Shortness of breath
- Weight loss
Cat dewormers are a type of medication that kills the larvae and adult parasitic worms. There are several types of over the counter and prescription dewormers for cats available.
These meds are usually administered in liquid or tablet form and contain active ingredients, such as:
- Pyrantel pamoate
Dewormers for cats can be hard on the body, since a cat with a severe infestation may already be weak, malnourished, and may have lost a lot of weight. Products such as ivermectin can treat ear mites, in addition to other types of parasites such as roundworms and can be used in combination with other types of dewormers. However, this dewormer requires a prescription.
Customer Request for Medication
As a customer, you can meet with your pet’s vet to discuss your options. The sort of medication a vet recommends is often more powerful than what you’ll find online.
For serious ear mites, roundworms or hookworm infections, you will need to speak to your veterinarian regarding prescription medication. A prescription dewormer can be required when over the counter products have failed to eliminate the parasites. A veterinarian will be able to order tests that can pinpoint what type of parasites you’re dealing with and order the proper medication.
Liquid or Tablets
You can choose products that are available in either liquid or tablet form. Most products that are in liquid form can be added to a cat’s food. These dewormers are commonly used to treat stray and feral cats as well, since you don’t have to come into contact with the cat to administer the medication. However, there is the concern that the cat will not eat all of the food or drink all of the water, which can mean they didn’t get the entire dose of the dewormers. With tablet form, you can be sure your cat gets the entire dose in one shot, however, it can be difficult to give a cat a pill, especially if the cat is aggressive or skittish. Both types of dewormers have their own advantages and disadvantages, so you should also choose dewormers based on your cat’s temperament.
